Application filed May 12,

useful Improvements in Conveyers, of which the following is aspecification.

This invention relates to improvements 1n saw machines and aims toprovide means.

operated by the saw operating mechanism for conveying blocks or piecesof wood cut by the saw to some remote point. p I Specifically stated,the invention conprises a conveyer, which has one end secured to theframe of the saw in position to re-. ceive the blocks or pieces ofwoodcut, the conveyer being driven by the saw operating means. I One ofthe principal objects of the invention is to provide a conveyer in whichfriction is reduced, so as toreduce the amount of power required for itsoperation to permit of its being driven'by the saw driv ng means, andfor this purpose the conveyer is I operated over anti-friction ribs orrods, over which the sawed block also travels so that the maj ority. offriction is overcome.

' Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanyingdrawings.

In the drawings:

Figure 1 is a plan view of a portion of a saw operating mechanism havingthe invention applied thereto.

Figure 2 is an end elevation of the same.

Figure 3 is a side elevation.

Figure 4;is a longitudinal section through the conveyor. 1

Figure 5 is a transverse sectional view of the same.

Referring to thedrawings in detail, wherein like characters of referencedenote corresponding parts, the machine includes a frame 10, upon whichis mounted a saw shaft 11, operating in bearings 12 secured to theframe. Mounted upon the shaft 11 in the usual manner is a circular saw18, the shaft also having mounted thereon a pulley 14:, which is drivenby a belt 15, operated by any suitable source of power.'

The conveyer, which includes outwardly inclined side wallsv 16 risingfrom and in contacting engagement with the side edges of a downwardlyinclined bottom 17, has

one end suitably secured to the frame 10, be-

neath the saw and in proper position to r'eceive'the blocks or pieces ofwood cut. Mounted in bearings 18, also-securedto the frame 10, is ashaft 19, the latter being disposed transversely of the trough formed ofthe side walls 16 and the bottom 17 At. the

opposite end of the trough is a transversely disposed shaft 20, theshafts19 and 20 carrying sprockets 21 arranged upon each side of thetrough, over which" travels chains 22.." .Secured to each of the chainsand disposed transversely of the trough are. substan' tially' L shapedcarriers 23, the latter bear 7 ing upon and traveling over spacedlongitudinally disposed metallic rods 24: arranged longitudinally withinthe bottom of the" trough. The upper flight of the chain operates withinthe trough and having their.

ends bent downwardly to conform with the curvature of the turning pointof the chains,

while the lower flight operates beneath the same. The sides ofthe troughposition by suitable braces'25.

The shaft 19 extends beyond one, of the are .held in I side edges of thetrough and has secured thereon 'a beveledgear 26, which'is engaged 10.The shaft 28 has secured thereon a puland driven by abeveled pinion 27mounted upon one end of a counter-shaft '28, which revolves in bearingssecured to the frame ley 29, which is disposed beneath and in contactwith the belt 15, so that an opera: v I

tion of this beltwillimpart motion to the shaft28 to drive the gears 26land 27 and operate the conveyer. The gears and pulley are soproportioned as to materially reduce,

In the operation of the invention, the

the speed of travel oroperation ofthe conblocks or pieces of woodcut bythe saw 13 will fall into the troughupoh the conveyer or uponthe ribs orrods 24: and be carried over these ribs or rods in a manner to'materially reduce friction, so that the amount of power necessary for theoperation of the con'veyer is reduced, permitting the same to beoperated by the saw operating mechanism without increasing the power ofthe latter. I

The invention is susceptible of variouschanges in its form, proportionsand minor details of construction and the right is here aim.

A conveyer' of the character described comprising a bottom Wall arrangedat an incli'nation and supported at its lower end, outwardly inclinedside Walls rising from said bottom wall and in contacting engagementWith the side edges thereof, transversely disposed shafts journalled inthe ends of the bottom Wall a sprocket carried by the ends of eachshaft, chains trained over m the sprockets, substantially L-shapedcarspacedparallel longitudinally disposed rods bent downwardly at theirends to conform to the curvature of the turning point of said chains andbeing secured to and spaced from the bottom Wall as and for the purposespecified.

' In testimony whereof I afiix my signature.
